Question

Sebuah kubus ABCD EFGH. Diketahui Panjang Diagonal Ruang AG = 24cm, maka volume kubus adalah?

Answer 1

Diagonal ruang kubus = 24
s√3 = 24
s = 24 / √3 >> 8√3 cm

V = s³
   = (8√3)³
  = 1536√3 cm³

Answer 2

Diagonal ruang kubus = s√3 = 24 cm
jadi s = 24/√3
s = 24/√3 x √3/√3
s = 24√3 / 3
s = 8√3

V = s³ = (8√3)³ = 512 x 3√3 = 1536√3
